perf tools: Record events info also when :record suffix is used.
You can enable a counter's PERF_SAMPLE_RAW attribute in two
fashions:
- using the -R option (every counters get PERF_SAMPLE_RAW)
- using the :record suffix in a trace event counter name
Currently we record the events info in a trace.info file from
perf record when the former method is used but we omit it with
the latter.
Check both situations.
